WHEEL-MOUNT FDR SPINNING-MACHINES.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed. July 18, 1914. Serial No. 851,681.

To all whom it may concern:

Be it known that 1, CHARLES W'. BOARD- MAN, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in VVheel-Mounts for Spinning-Ma chines, of which the following is a specification.

My invention relates to improved means for removably supporting and locking in position ina holder or frame member, a freely revoluble belt take-up or tension-pulley. Pulleys of this general character are employed in connection with textile spinning, twisting, and winding or spooling machines.

In the invention forming the subject of this application for patent the holder or yoke member is provided with a pair of integral depending arms each having an open bearing-box or seat to which is hinged a bifurcated swinging latch arranged to press laterally against the bearings removably mounted in the respective seats. Cocperating with the latch is a movable catch or keeper adapted to positively lock or clamp the respective bearings in the normally closed position; the said bearings, it may be stated, carry a revoluble axle to which the take-up or tension-pulley is or may be rigidly secured.

In the appended drawing, Figure 1 represents a front elevation of a yoke provided with my improvement, the several members being shown in the normally closed and locked position; Fig. 2 is a corresponding side elevation; Fig. 3 represents the latch in the dropped condition, unlocked, the bearing, axle and pulley being removed; Fig. 4 is a top plan view of the keeper or catch detached; and Fig. 5 is a perspective view of the latch member.

A, in the drawings, indicates a take-up or tension-pulley secured to a center axle a revolubly mounted in the bearings d.

B, represents a suspended forked yoke normally carrying the said pulley, axle and bearings. The yoke is provided with a pair of parallel, downwardly extending arms 6 terminating in enlarged open, box-like recessed seats Z2 arranged to receive and support the said bearings therein. The lower member of each seat may be extended in front in the form of cars 6 these in turn have perforations 6 arranged to freely receive the respective ends or journals 0 of the latch C, later described.

The upper or head portion of the yoke is provided with a central extension or neck 6 connected to a suitable hanger member ii. The bearing members cl of the yoke are removably fitted and supported in the recessed seats 6 as clearly represented in Figs. 1 and 2. The latch element C is forked and preferably formed from a piece of suitable comparatively stiff metal,having a degree of resiliency. The latch is provided at its upper end with a central cross tie 0 which also serves as a handle member in opening and closing the latch; the metal is further bent to produce a pair of parallel arms 0 0 extending downward from the ends of the cross tie and terminates in opposed pivots or trunnions 0 mounted to swing in the perforations of said ears 5 A suitable keeper member f encircles the neck 72 of the yoke; the keeper being provided on its lower edge with ahook-like clip f constructed to engage the tie a of the latch when the latter is swung upward to its normally closed and locked position. The member It may be employed to limit the upward movement of the keeper; the keeper when thus elevated causes the latch to be released from it and permits it, the latch, to be swung downward, thereby simultaneously disengaging the arms of the latch from the respective bearings, after which the bearings may be readily removed bodily from the yoke. Upon thus releasing the latch the keeper may drop by gravity to its lower or normal position, substantially as indicated in Fig. 3.

In assembling the parts, the pivots c of the arms 0 of the latch are mounted to rock in the yoke or frame. When the latch is normally closed its arms press snugly against the adjacent surfaces of the bearings with sufficient force to keep them (the bearings) in position. At the same time the clip or hook of the keeper engages the tie part 0 of the latch and confines the latter be tween the clip and contiguous portion of the yoke, the resiliency of the latch against the keeper meanwhile maintaining the parts in position against accidental movement or release. The device is inexpensive to manu facture, easily and readily actuated, conveniently accessible and at the same time forms safety locking means for the bearings and tension-pulley.

I claim 1. A wheel-mount for the tension-pulleys of spinning-machines, the same comprising a bifurcated yoke, said yoke having downwardly extending parallel arms and an upwardly extending central neck, the lower portion of each arm of the yoke having an open lateral recess, a bearing member removably seated in each recess, a tension-pulley revolubly journaled in said bearings, a swinging latch hinged in the yoke at a point below the bearings so as to snugly engage the exposed face of the respective bearings, and a keeper member slidably mounted on said neck portion of the yoke, said keeper having a hook on its underside arranged to engage a member of the said latch and lock it in the normally closed position.

2. In a wheel-mount for tension-pulleys of spinning machines, the combination with a bifurcated yoke or frame having downwardly extending parallel arms provided with alining recesses formed in their lower ends, of bearings removably seated in said recessed portions, a tension-pulley journaled in the bearings, a bifurcated resilient latch member having the lower or free ends of its arms mounted to swing in the yoke at a point below said bearings, and a guided selfdropping keeper arranged to interlock with the latch so as to yieldingly press the latter against the bearings and hold them against displacement.

3. The combination in a textile spinning machine, of a mount for tension-pulleys, said mount consisting of a fork-like frame having laterally separated arms, each arm having an open recessed seat, bearings removably mounted in said recesses, a tensionpulley positioned between the arms of said frame and revolubly journaled in said bearings, a resilient latch swinging in the frame, and a self-dropping keeper member provided with a lug arranged, when in use, to engage the latch and yieldingly hold it securely in the normally locked position, and at the same time causing the latch to yieldingly press against a face of said hearings to retain-them in position.

In testimony whereof I have affixed my 50 signature in presence of two witnesses.

CHARLES W. BOARDMAN.
